After snaking the sewer line twice in one week,the plan is to put in a clean out.The plumber had an excavator find (BY a beeping noise)the spot and the depth where the line leaves the house.It shows 5 and1/2 ft. deep which sounds pretty odd.The lot runs flat some 200ft to get on to the sewer line.House is on a slab and well is very close to the "spot".Big trees in yard,cause of the problem.House built in '53.
